Well, if you DO have the ratchet-type levers, it should only be a matter of setup on your MFU, which also can prove a bit annoying sometimes.

Lots of guys here have experienced troubles with their MFU´s and quite often, it turns out that a simple re-calibration is the trick

Sometimes, also the selector-switch on the MFU control-panel is in a wrong position, either from handling the car, or simply having pushed the switch by accident..
Also, you cannot always trust the channel-description in the manual, (using the stickers for the cables), but have to make you own setup to match the radio you use.
About the colours, i really think that turqoise-thing goes well with the gunmetal, but i would have chosen another design, as the entire sleeper in that colour makes the sleper look very "boxy" along with the rest of the shell, which isn´t exactly the way you would describe the Knight from the beginning, being very aerodynamic.. Sorry.

I think the "normal" scheme where the sticker-stripes had been replaced with the turqoise would have looked smashing!! Especially along with the roof and fender-details in the same colour.
Anyway, I hope you get your MFU up and running.. And if not, just bin it, and get some new stuff for the truck. , hee-hee.
All the best..
